Chapter 8

Question 1

Catabolism is

Answer 1

A cellular process . Larger molecules to smaller

Question 2

Anabolic pathways do what

Answer 2

consume energy to build polymers from monomers

Question 3

First law of thermodynamics

Answer 3

Energy cant be created or destroyed

Question 4

When happens when energy is transformed

Answer 4

Entropy in the universe increases

Question 5

Second law of thermodynamics

Answer 5

Entropy increases when energy is transferred or transformed

Question 6

Potentional energy is

Answer 6

Chemical. waiting to be released

Question 7

G=

Answer 7

Free energy

Question 8

H=

Answer 8

Total energy

Question 9

S=

Answer 9

Entropy

Question 10

T=

Answer 10

Temperature

Question 11

Formula

Answer 11

G=H-TS

Question 12

Energy coupling/Energy cycle needs ATP bc

Answer 12

it provides the energy between exergonic and endergonic reactions

Question 13

ATP phosphates

Answer 13

3 phospates

Question 14

ADP phosphates

Answer 14

2 phospates

Question 15

RNA phosphates

Answer 15

1 phosphate

Question 16

Energy coupling/Energy cycle is

Answer 16

The transfer of free energy from catabolic or anabolic pathways

Question 17

ATP releases energy and during this

Answer 17

it releases inorganic phosphates which can activate other molecules

Question 18

What do enzymes do

Answer 18

Increase rate of chemical reaction

Question 19

Thermodynamic barrier AKA

Answer 19

Activation energy

Question 20

A thermodynamic barrier has to

Answer 20

be overcame to allow reacants to do stuff

Question 21

Cause of expected reaction not working

Answer 21

Thermodynamic barrier cant be overcome

Question 22

In induced fit model

Answer 22

Binding the substrate changes the enzyme active site

Question 23

Enzymes speed up reactions because

Answer 23

They lower the amount of activation energy needed

Question 24

Increased temperature can have serious consequence because

Answer 24

it can change the folding of enzyme and therefore their function

Question 25

Competitive inhibitors

Answer 25

Prevents an effect

Question 26

Noncompetitive inhibitors does

Answer 26

the opposite of an enzyme (Decreases rate)

Question 27

ATP and ADP cycle

Answer 27

ATP stores energy for cellular work, it is used, phosphate is lost creating ADP, then phosphate is picked
back up creating ATP and the cycle continues

Question 28

Endergonic reaction

Answer 28

positive energy moving into system

Question 29

Catabolic pathways release energy by

Answer 29

breaking bonds

Question 30

Anabolic pathways do what with energy

Answer 30

Consume/take in

Question 31

Exergonic reactions

Answer 31

lose/ use energy

Question 32

Endergonic reactions

Answer 32

move energy into a system
